Abstract

An antenna module and an electric device are provided. The antenna module includes a first slot antenna unit and a second slot antenna unit. The first slot antenna unit is coupled to a radio frequency (RF) unit. The second slot antenna unit is coupled to the RF unit. The first and second slot antenna units are embedded in a wireless communications dongle, and the wireless communications dongle operates as a modem to transmit or receive a wireless signal to or from a wireless telephony communications network for a computer via the first and second slot antenna units when the wireless communication dongle connects to the computer. Accordingly to the invention, an electromagnetic energy absorption rate of the antenna module can be raised.

Description

technical field [0001] The present invention relates to a kind of single input / multiple output (single input / multiple output, SIMO), a kind of multiple input / single output (multiple input / single output, MISO) or a kind of multiple input / multiple output (multiple input / multiple output) output, MIMO) antenna module and electronic device, especially related to a SIMO, MISO or MIMO antenna module and electronic device with improved electromagnetic wave energy absorption rate (Specific Absorption Rate, SAR). Background technique [0002] The electromagnetic wave energy absorption rate is used to evaluate the rate at which the human body absorbs radio frequency energy when the human body is exposed to a radio magnetic field. It is defined as watts of energy absorbed per kilogram of tissue. The evaluation of electromagnetic energy absorption rate is usually performed on the whole or as an average of a small sample volume (typically 1 or 10 kg of tissue). This value quotes the hig...
